A floating apparatus for providing pressurized air to a submerged swimmer. A container is sealed and waterproofed so that it will float on the surface of the water and has an inlet above the water and an outlet below the water. The outlet is adapted to be coupled to a hose which will provide air to the submerged swimmer. The inside of the container houses a pump which couples the inlet to the outlet and forces pressurized air through the outlet. The pump is driven by an electric motor within the container.
